Given that the company is called Mutable AI and they called the product (?) Auto Wiki then I have to assume that they auto-generated the wiki. But I agree that the wording is ambiguous and could be interpreted as "we manually created the wiki".

> So we went back to step 1, let’s understand the code, let’s do our homework, and for us, that meant actually putting an understanding of the codebase down in a document — a Wikipedia-style article — called Auto Wiki. The wiki features diagrams and citations to your codebase.

(Edit) Homepage makes it clear they're talking about ML-generated wiki https://mutable.ai/
